Reconstructing Africa's Climate: Solving the Riddle of Rainfall. November 16, 2018.
To grasp the significance of global warming, and to confirm its connection to human activity, you have to know how climate has changed in the past. Scholars of past climate change know that understanding how climate has varied over historical timescales requires access to robust long-term datasets. This is not a problem for regions such as Europe and North America, which have a centuries-long tradition of recording weather with instruments. More
Two Decades from Disaster? The IPCC's "Global Warming of 1.5° C." October 11, 2018.
International climate change agreements have long aimed at limiting anthropogenic global warming to 2°C Celsius, relative to so-called “pre-industrial” averages. Yet in early 2015, more than 70 scientists contributed to a report that warned about then-poorly understood dangers of warming short of 2° C. Several months later, Parties to the United Nations Framework Convention on Climate Change (UNFCCC) met in Paris and reached an agreement to keep global warming to “well below” 2° C. The Paris Agreement invited the Intergovernmental Panel on Climate Change (IPCC) to prepare a special Assessment Report. More
Is There a Better Way To Do Climate History? Testing a Quantitative Approach. August 31, 2018
Until recently, it was notoriously difficult to connect today’s extreme weather with the gradual trends of climate change. Scientists shied away from saying, for example, that catastrophic droughts or severe hurricanes reflected the influence of anthropogenic global warming. More
Are Woodland Caribou Doomed by Climate Change? July 26, 2018.
In May 2018, woodland caribou were declared functionally extinct in the United States. Across the Canadian north, woodland caribou have disappeared from roughly half their 19th century range. Is climate change dooming woodland caribou? Or are managers using climate change as an excuse to avoid making difficult policy decisions? More
A Conversation with Dr. Dagomar Degroot: Resilience and Adaptation in the Little Ice Age. June 15, 2018.
In the eighth episode of the Climate History Podcast, PhD candidate Robynne Mellor (Georgetown University) interviews Dr. Dagomar Degroot, director of HistoricalClimatology.com, about his new book: The Frigid Golden Age: Climate Change, the Little Ice Age, and the Dutch Republic, 1560-1720. Dr. Degroot is an assistant professor of environmental history at Georgetown University, where his research focuses on societal adaptation and resilience to climate change, and the environmental history of outer space.

Ecological Militarism: The History of the Military’s Relationship with Climate Change. May 25, 2018.
Many historians have discussed the influence of the Cold War on the development of specific disciplines within the broader field of earth science. However, few have touched on U.S. military’s study of climate change, an interest that accelerated during the Cold War. The decades-long studies sponsored by the Departments of Defense and Energy in the Cold War produced led to many attempts to transform the earth itself into a political and environmental weapon. More
Introducing the Tipping Points Project. April 30, 2018.
In late 2016, Randall Bass, vice provost for education at Georgetown University, asked me to help design and teach a pilot project at Georgetown University that would experiment with a new way of introducing climate change to undergraduate students. The Core Pathway on Climate Change initiative, as we came to call it, allowed students to mix and match seven-week courses - "modules" - to find their own pathway through the scholarship of climate change.

North Atlantic Right Whales From Their Medieval Past To Their Endangered Present. March 21, 2018.
2017 was a calamitous year for the North Atlantic right whale. The final count of the 2017 "Unusual Mortality Event" was eighteen animals. Fourteen North Atlantic right whales were found dead from the Gulf of Saint Lawrence to Cape Cod between June and December, with an additional four strandings and entanglements through the year. More
A Frigid Golden Age: Can the Society of Rembrandt Teach Us About Global Warming? February 27, 2018.
Earth’s climate is changing with terrifying speed. Humanity has strengthened a greenhouse effect that has now warmed the planet by roughly one degree Celsius. The scale, speed, and causes of today’s global warming have no precedent, but of course natural forces have always changed Earth’s climate. We now know that these changes were big enough to shape the fates of past societies. Most confronted disaster, but a few seemed to prosper in spite of – and in some cases because of – climate changes. Perhaps the most successful of all emerged in the coastal fringes of the present-day Netherlands. More
Icebreaking in the Gulf of Bothnia: A Passenger’s Perspective. January 11, 2018.
This past winter I was fortunate to join the Arctia Otso icebreaker in the Gulf of Bothnia, Finland, from March 2 to March 24, 2017. I had sailed the Northwest Passage aboard the Canadian Coast Guard ships Sir Wilfrid Laurier and Louis S. St-Laurent in 2015. Going to Finland to travel on an icebreaker for 20 days was my next big step as a Canadian scientist. More
Looking Back, Looking Forward: A Historian Goes to COP23. December 21, 2017.
I joined the most recent UN Climate Change Conference in Bonn with a delegation from Monash University, which also included legal scholars, renewable energy specialists, and science communicators. The opportunity to observe and participate in the activities that accompany the negotiations was too good to pass up. More
